To prevent an anemic domain model in Spring Boot, design rich domain models by enforcing aggregate boundaries, immutability for value objects, and domain event handling. This replaces anemic CRUD patterns by aligning code directly with complex business rules and real domain concepts.

You need an anti-corruption layer in domain-driven design when integrating external models or subsystems. It isolates external models from your domain, ensuring that external dependencies do not corrupt your core domain logic and preserving the integrity of your bounded contexts.

Implement aggregates in Spring Boot by enforcing root-centric access and strict boundaries. Define value objects as immutable entities with equality determined by value, ensuring invariants are maintained within the aggregate to support complex business rules consistently.

The best way to handle domain events across bounded contexts is to capture intent and publish events after state changes. This approach ensures aggregate consistency and maintains clear boundaries between different domain segments within complex Spring Boot applications.

Domain-driven design is not suited for simple CRUD applications. It is designed specifically for projects with complex business rules, multiple aggregates, and domain events, where enforcing rich domain models prevents the limitations of anemic CRUD patterns.
